Impossible.I dont certify that Mahajan is a very claean Man.As any Indian politician he has also got certain greysides but not to the extent as told by his brother.
It is just the comment we often hear about politician by Middle level or lower economic level people about amassing wealth this is also like that.

Its possible.Now see the situation of his son.He snorted cocaine using 500 Rs note(where Gandhi’s photo lies).Like Sharad Pwar ,Pramod was a king of corruption.whether its Reliance/Jet Airways/Spice Jet Mahajan did not hide the fact privately that he received loads of suitcases from them.His son who is now recovering in Appolo is no less fraud.
